5/**
6 * Global Escape → abort. Mirrors Cowork's `escAbort.ts` but without Electron:
7 * CGEventTap via `@ant/computer-use-swift`. While registered, Escape is
8 * consumed system-wide (PI defense — a prompt-injected action can't dismiss
9 * a dialog with Escape).
10 *
11 * Lifecycle: register on fresh lock acquire (`wrapper.tsx` `acquireCuLock`),
12 * unregister on lock release (`cleanup.ts`). The tap's CFRunLoopSource sits
13 * in .defaultMode on CFRunLoopGetMain(), so we hold a drainRunLoop pump
14 * retain for the registration's lifetime — same refcounted setInterval as
15 * the `@MainActor` methods.
16 *
17 * `notifyExpectedEscape()` punches a hole for model-synthesized Escapes: the
18 * executor's `key("escape")` calls it before posting the CGEvent. Swift
19 * schedules a 100ms decay so a CGEvent that never reaches the tap callback
20 * doesn't eat the next user ESC.
